Django 中字段选择的“人类可读”值

Question

PAYCODE_BLUEPAY = "BLUEPAY"
PAYCODE_HEARTLAND = "HEARTLAND"
PAYCODE_1STPAY = "1STPAYMENT"
PAYCODE_CHOICES =(
    (PAYCODE_1STPAY, '1St Payment'),
    (PAYCODE_BLUEPAY, 'Bluepay Payment'),
    (PAYCODE_HEARTLAND, 'HeartLand Payment'),

)

class Payment(models.Model):
    paymentmethod = models.CharField("Payment Method", max_length=20, choices = PAYCODE_CHOICES, blank=False, null=False)

    def __str__(self):
        return self.paymentmethod

方法 __str__(self) 将 return BLUEPAY 或 HEARTLAND 或 1STPAYMENT。但我想要 __str__(self) return 1St Payment, Bluepay Payment 或 HeartLand Payment.

请给我解决方案。谢谢。

Answer 1

def __str__(self):
    return self.get_paymentmethod_display()

见get_FOO_display()
